Choose four different digits from 0 to 9. Put each of them once in every row and every column. Each outlined shape shows a target number in its corner. Do the circled operation inside a pair of linked boxes first, then the one between pairs. Linked boxes with no operation join into one number: a 3 and a 5 make 35.
Every row and every column is an equation that reads left to right, or top to bottom. Fill the dashed boxes so all six equations are true. Use each number tile once.
